MDD025C-N-100-N2K-040MA1
The MDD025C-N-100-N2K-040MA1 is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a compact servo unit, it integrates into digital drive systems where fast rotational motion is needed for feeders, light-duty actuators, or indexing tables in automated production lines. The housing and balancing are both standard, providing straightforward mechanical installation, while the standard shaft end omits a secondary shaft on side B to keep the overall length short.
Under continuous stall conditions, the motor develops 0.90 Nm of torque without overheating. High-speed processes are supported by its rated velocity of 10,000 rpm, allowing quick indexing or spindle-style duties when the controller commands full frequency. For holding a position during power loss, the integrated blocking brake supplies 1.0 Nm of static torque, and this holding force is applied mechanically through internal friction plates when the brake is engaged. The flange registers to fixtures through a centering diameter of 40 mm, ensuring concentric alignment to couplings. All power and feedback conductors exit on Side A, so cable routing can be planned from one face of the cabinet or robot arm. Rotary power is transferred by a keyed shaft, and the keyway helps prevent slippage between the shaft and the driven hub during acceleration or reversal.
Position data originates from an Integrated absolute encoder, providing the drive with multi-turn angle information immediately after power-up. For real-time current loop closure, the motor also carries Resolver feedback, giving analog sine-cosine signals that tolerate electrical noise common in factory environments. Because the unit is supplied without a shaft seal, installation areas must be kept free of coolant splash or oil mist to avoid bearing contamination. Length code C matches the 025 frame diameter, giving the motor proportionate inertia for quick servo response without excess overshoot.
